IPTV-based systems offer acquisition and distribution of content from numerous channels with protected end-to-end conditional access. In adopting IPTV-based systems for seamless transport and blackout management of the content, service providers would need an IPTV-based transport architecture that accommodates their existing infrastructure and provides transparent live events content blackout management. In the spectrum of service providers some have no physical infrastructure at all and some have the entire suite of infrastructure and services. Therefore, the present invention provides a new IPTV-based transport system architecture that can accommodate the spectrum of service providers, including tier-1, tier-2 and tier-3 telcos. Such architecture includes double-layer encryption and bulk decryption in addition to encapsulation that allows seamless transition from programs to alternate programs in designated blackout areas.
